Jason Lowe commented on YARN-8649:
----------------------------------
Thanks for updating the patch! +1 lgtm. While reviewing it looks like there's
a window where we can leak resources on the local disk if containers are killed
while localizing and we don't get around to getting the localizer killed before
it finishes localizing a resource. Filed YARN-8703 to track that separately.
Committing this.
> Similar as YARN-4355:NPE while processing localizer heartbeat
